Hi I am new on here I signed up because ive been starting to kind of worry about something that im going through. I usualy feel all tense and I feel nervious and stuff. Like for example I will be driving on the freeway I feel all tensed up I keep lookin over at my arms or I keep looking around and I always drift over to the other lanes cause I cant keep myself focused to the freeway. I feel really tense and sometimes I feel all tensed up where I have shortness of breath. By any chance could this be stress? When I was younger I used to be fatter and I ate very very unhealthy my doctor said I have made my heart work harder so now my heartbeat is a little bit higher than normal usualy very little he told me to do some cardio to get it back into shape but im still the same. Iono maybe that has to do with what im going through does anyone have any idea what this could be and if you do is there anything I can do to fix this? Im thinking of geting on the tredmill a little bit more helping out my heart a little more. Any help will be helpfull.

Thank you
